Nintendo is suspending service of its 3DS messaging app, Swapnote, because according to the company it’s being used by minors to exchange offensive material. Apparently Nintendo is learning late the golden rule of technology: if you built it, they will use it for pornography.

"Nintendo has learned that some consumers, including minors, have been exchanging their friend codes on Internet bulletin boards and then using Swapnote (known as Nintendo Letter Box in other regions) to exchange offensive material," reads a statement on Nintendo's site. "Nintendo has been investigating ways of preventing this and determined it is best to stop the SpotPass feature of Swapnote because it allows direct exchange of photos and was actively misused."

Swapnote and Special Notes are shut down as of this article in all regions. Nintendo says it will not continue service until its able “to provide a positive experience for all consumers and limit the risk of any inappropriate activity or misuse of a service.”

Nintendo introduced a photo-sharing feature to Swapnote last April allowing users to attached photos and audio files to a messages opening up a whole new world of possibilities.
